At present, most of drawer locks popular in the market adopt mechanical locks, unlocking and locking through a key are still the main modes of opening and closing locks, the traditional mechanical locks are gradually replaced by locks such as the existing popular coded locks due to poor safety performance, the safety performance of the coded locks is relatively improved, but the passwords of the coded locks also have the risk of being cracked, if users forget the passwords, great inconvenience is brought to the users, along with the development of the economic society, the improvement of the living standard of people and the continuous progress of fingerprint identification technology, the requirements of people on the safety of the locks are higher and higher, the fingerprint locks are also gradually applied to the daily life of people, the traditional fingerprint locks mainly comprise a fingerprint sensor, a control circuit and a lock body, fingerprints are collected through the fingerprint sensor, and then the fingerprints are identified by utilizing the control circuit, then control the opening and closing of tool to lock body, current fingerprint identification tool to lock mainly has the reliability not high, the structure is complicated and install and use defects such as inconvenient, and this application range that just makes current fingerprint identification tool to lock has just received very big restriction.

And current fingerprint lock physique is big, occupies that the drawer position is many, and fingerprint inductor and lock body an organic whole set up simultaneously, need reform transform the drawer in order to be suitable for the fingerprint lock by a wide margin when installing on the drawer, and it is very inconvenient to install and use.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model relates to a fingerprint drawer lock of novel structure.

The utility model adopts the following technical scheme:

A fingerprint drawer lock comprises a lock body, a fingerprint sensor and a lock tongue baffle, wherein the lock body comprises a shell, a speed reducing motor, a power supply, a rotary disc and a lock tongue are arranged in the shell, a guide passage for the lock tongue to enter and exit is arranged in the shell, the power supply is connected with the speed reducing motor, the output end of the speed reducing motor is fixedly connected with a gear, the rotary disc is rotatably connected with the shell, tooth grooves which are uniformly arranged in an arc shape are arranged on the surface of the rotary disc along the circumference, the gear is meshed with corresponding racks for transmission, a push rod is fixedly arranged on one side of the rotary disc, a movable groove is correspondingly arranged on the lock tongue, the push rod is matched and inserted into the movable groove, the push rod can move up and down along the movable groove, along with the rotation of the rotary disc, the push rod drives the lock tongue to enter, the Hall element is communicated with the control circuit through a lead.

Preferably, the power source is a battery, and a battery jar is arranged in the shell.

preferably, the shell is provided with a login button and a delete button, the login button and the delete button are communicated with the control circuit through a wire, and the login button and the delete button are matched with the fingerprint sensor to guide in and store and delete fingerprints in the fingerprint identification library.

preferably, the lock body is arranged in an elongated shape.

Preferably, the four corners of the shell are provided with mounting holes.

The utility model has the advantages that: (1) the fingerprint drawer lock is small in size, simple in structure and convenient to assemble and use; (2) the lock body and the fingerprint sensor are separated, and only are communicated through the lead, the lock body is fixed in the drawer, the fingerprint sensor is independently fixed outside the drawer, the use and installation are convenient and simple, and the drawer is greatly improved without being matched with the installation of a fingerprint lock.

Drawings

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic view of an internal structure of the present invention;

Fig. 3 is a schematic structural diagram of the lock tongue of the present invention;

In the figure: 1. the lock comprises a lock body, 2, a bolt baffle, 3, a fingerprint sensor, 4, a bolt, 5, a battery jar, 6, a login button, 7, a delete button, 8, a mounting hole, 9, a speed reduction motor, 10, a gear, 11, a rotary table, 12, a tooth groove, 13, a push rod, 14 and a movable groove.

Detailed Description

The technical solution of the present invention is further described in detail by the following specific embodiments in combination with the accompanying drawings:

Example (b): as shown in attached figure 1, attached figure 2 and attached figure 3, a fingerprint drawer lock comprises a lock body 1, a fingerprint sensor 3 and a lock tongue baffle 2, wherein the lock body comprises a shell, a speed reducing motor 9, a power supply, a rotary disc 11 and a lock tongue 4 are arranged in the shell, a guide channel for the entrance and exit of the lock tongue is arranged in the shell, the power supply is connected with the speed reducing motor, the output end of the speed reducing motor is fixedly connected with a gear 10, the shell is rotatably connected with the rotary disc, tooth grooves 12 which are uniformly arranged in an arc shape are arranged on the surface of the rotary disc along the circumference, the gear is in meshing transmission with corresponding racks, a push rod 13 is fixedly arranged on one side of the rotary disc, a movable groove is correspondingly arranged on the lock tongue, the push rod is matched and inserted into the movable groove 14, the push rod can move up and down along the movable groove, be provided with hall element near spring bolt department in the casing, be provided with magnet on the spring bolt baffle, hall element passes through wire intercommunication control circuit, and the power is the battery, is provided with battery jar 5 in the casing, is provided with login button 6 and delete button 7 on the casing, and login button and delete button pass through wire intercommunication control circuit, and login button and delete button cooperate the leading-in storage of fingerprint inductor and delete the fingerprint in the fingerprint identification storehouse, and the lock body is rectangular form setting, and mounting hole 8 has been seted up to casing four corners.

When the fingerprint drawer lock is installed, the lock body is fixed on the inner side of the drawer through a bolt, the fingerprint sensor is fixed on the outer side of the drawer, a small hole is formed in the drawer between the fingerprint sensor and the lock body and used for penetrating through a communicated wire, the lock tongue baffle is fixed on the upper edge of the lock body in the drawer, which is right corresponding to the lock tongue, after the installation is completed, the login button is opened, the fingerprint of a user can be stored through the fingerprint sensor and used, when the fingerprint drawer lock is used, the user presses the fingerprint onto the fingerprint sensor, the fingerprint sensor senses the forward rotation of the speed reducing motor through the control circuit, the speed reducing motor drives the turntable to rotate forward, the turntable drives the lock tongue to retract into the shell, so that the drawer can be opened, when the drawer is locked, only the drawer needs to be closed, because the Hall element in the lock body is right opposite to the magnet on, the rotating disc is driven to rotate reversely, so that the lock tongue is driven to extend out to abut against the lock tongue baffle, and the drawer is locked and cannot be opened.
